To all whom it may concern: Be it known that i, JOSEPH'J: CIJRRY a citizen of the United States, reslding in Phil.-

adelphia, Pennsylvania, have inventedcertain Improvements in Knitting-Machine's, of

which the following is aspecification.

My invention relatesto certain improve; ments' in automatic circular-kn tting machines of the type employing two series of simultaneously-reciprocated bearded, needles capable of producing either plain work or lacework, or a combination of the two. Heretofore in this class of machines the com-,

binations were limited, which limited "the designs. Q

The object of my invention is to Widen the scope of a machine of the above type so that various designs can be made whlch'were not obtainable in machines of this type.- This.

object I attain by so designing themachine that alternate tucking needles or sets of tucking-needles can be .so arranged as to knit plain work, while intermediate tuckingneedles or sets of tucking-needles are so acted upon as to produce tuck-stitches. p

In the accompanying drawings, Figure 1 is a plan viewof sufficient of a circular automatic knitting machine using bearded needles to illustrate my invention. -Fig..2 is a rear view of the machine illustrated in Fig. 1. Fig. 3 is an end view. "Fig. 4 is a sectional view of a portion of the machine on the' line 4 4 Fig. 1. Fig. 5 isa sectional View on the line 5 5, Fig. 1. Fig. 6 is a diagram plan view of a portion of Fig. 1. I Fig. 7- is a sectional perspective view of a portion of the head of I showing the jacks and the platering and illustrating one design of fabric capable of being produced on this machine.

A is the frame of the machine.

-B is the needle-cylinder,

B is the head ofthe cylinder.

B is the web-cylinder mounted within the needle-cylinder.

b b are the needles arranged in-the grooves of the needle-cylinder, and these needles are of the bearded type, some being flanged when arranged for heel and toe work; but it will be understood the machine maybe provided with an entire setv of plain needlesior tubular work.

C the sinker-head, constructed in the usual manner and in which the sinkers are mountml. This sinker-head has two projecting flanges c a, between which is mounted shown in the beard of the needles.

the shogging-ring D. The ringin the present instance is made in halves, one half having an arm d and the other half having an arm d, so

that one may be thrown out of gear while the other is operating, this being done when knitting hosiery during the making of they heel and toe.

In the periphery of each ring are camgrooves (1 (clearly shown in Fig. 2,) and projecting into these grooves from the flange c are pins 0 and as these pins are stationary any shogging movement of either half of the ring will cause said half to be lowered or raised.

E are the tuckin -jacks, and E the blind jacks. Thesetwo forms of jacks are clearly perspective view, Fig. 7. Each tucking-jack has the usual head eand the rear extension .6, and projectin from the under side of the jack is a rounded portion which rests in the, groove in the cylinder-head and forms the pivot for the tucking-jack. The blind jacks have a projectin portion e which also rests in the grooves in t head, but are not pivoted, beingheld rigid by the overlapping flange of the sinker-head, which rests in the notch c at the upper corner of the said jack.

ff are the usual spiral springs in the form of rings, which /bear upon the tucking-jacks, tending to keep them in the normal position, as'clearly shown in Fig. 4. The jacks when in their normal position act to' close the Heretofore the shog'-' ging-rings when depressed acted to throw all ofthe' tucking-jacks out ofnormal position and free of the needles, so that the beards of the needles would not close, therefore causing e cylinder.-

all the needles which were in line with the tucking-jacks to retain the old stitch, pro-'- (lucing a tuck-stitch, which, in fact, is an ele* ment of lacework.

By my invention, which I will now proceed to describe, the mechanism can be so controlled that either alternate tuckingjacks or sets of tucking-jackscan be moved out of their normal position while other tucking-jacks or sets of tuckingjackscan be allowed to remain in their normalv osition. Thus in the same course certain need es capable of tucking are knitting plain work while others of these needles areknitting tucked or lace work, and by providing means for shifting this mechanism the tucking-needles which were producing plain work will produce tucked work, and the tucking-needles which were producing tucked work will pro-' duce plain work.

I are closed by The plate-r1 mg I is made in alve's in the pres-f while jacks It will be understood that'my improved mechanism does not affect the needles which the blind jacks'for producing plain knitting.

Mounted directly under the shogging ring- D in the present instance is a ring I, having a series of segmental flanges i, which extend over the rear extensions of t' itucking-jacks E. This ring I will term hereafter a platerin as thesesegmental flangesi form plates which intervene between some of the tuckingjacks and the shoggingring, and the flanges are of sufficient depth that when the shogging-ring is depressed it will bear upon the ring I and the segmental flanges iwill act upon the rear extensions of the tucking jacks E, thusthrowing the tucking-jacks out of the path of-the needles, so that the beard ofthe needles will not be acted u on by said jacks.

ent instance to corres 0nd with the ;two-1par t shogging ring D, as 'il us'tratedin'Figs'. Land 6. The tuckingjacks which are 'noteunder the segmental flanges are free andremainim their normal osition, as the shogging-ring is not de resse to such anextentasto act upon t es'e jacks. This is clearly shown in Fig, 5 where the shogging-rin D )S de pressed and in its lowest position, ut clear of the'jack. It will be readily seen that itthe plate-ring I is shifted the flange will be moved over the rear extensions of their jacks, revio'usly'under the. control ofthe ring wili be-free and undisturbed." In" Fig. 71 have shown the tucking-jacks in groups of three, and the segmental-flanges i ofthe ring I are so spacedthat each alternate 2 will be-acted upon and thrown out" turns the rings-tea given-ergtent, so that-the cam-grooves will raise or lower the ring' la'sn I describedabove. The ringjisimad'e in two parts, so' -that one -'can' beop'erated independently of the other;

a is a bracket secured to the base A, --having a bearing a for a vertical spindle with bearing-lugs m m, which engage and actaste the arms d d of the shogging-r'ing in theordinary manner. This spindle M can ed and lowered by a cam-drumN h the noeditqn oi the rod a and the ic The spindle turned in its bearing carrying at its upper end an arm'-M, provided ed to he shaft courses before a change takes place. change is governed by a disk V, which has a. notch 11, sthe ratchet-wheel S and is so shaped as to i'hold the and 8 out of engagement with the by a pattern-wheel P, having lugs 10 on both sides, and on the spindle M is a forked arm m, which is actuated by the lugs p, so'that the arm and its spindle will be real rocatedas the lugs ass the arm. All the a ove-de scribed mec anism is common to this type of machine. 1 p

J J are the needle-carriers of the ordinary type, and mounted on the base A is a bracket a on which is mounted a rock-shaiitlc, having arms 7c, k 76. The arm k is forked at its outer end and engages a pin on the plate,

'SGCUIGd'iJO the needle-carrier J, so that as the needle-carrier is raised andr lowered motion will be imparted to'the rock-shaft 1c. Pivoted to the end of the armkf is apawl p'x,'which engages theteethp of the patterri-wheel P, and. ivoted to the endof the arm 7c is a pawl s, which is arranged to actuate the ratchetwhecl -S,g secured tdthe shaft S, which is mountedin bearings a secured to thelbase- A. "()ri the shaft is a bevelwheel s, mesh- 7 1 ing withaj pinion ton-a short vertical shaft 5 1, and on; the upper end of thisshai't is a disk t", having a'crank-pin t which is connected to; the plate-ring.

To accomplish this, I-so propor- "tion the parts thatwhen the pawl 8 acts upon;

certaintucking-jackswill be actuated by the The operation of this mechanism is as follows: As the pattern-wheel is intermittently rota-ted and the pin- 12 is traveling toward one arm of the lever V. the pawl s is being reciprocated, but slides upon the notched disk V of the ratchet-wheel S, so

clear of the teeth that it imparts no motion to the plate-ring;

P strikes the arm-of t e lever V it shifts the said notched disk so as to bring the notch!!! inthe path of the pawl s. The pawl will imme'- diately engage the teeth of the ratchet-wheel S ,moving the ratchet-wheel a given distance, causing the crank-pin t to move one-half a revolution, which in turn .causes'the platering to shift from one of its positionsto the other, and as 'soon as the pin p passes the lever V the spring 12 returns the said lever to its normal position, and with it the notched 8 out of engagement with the ratchet-teeth.

There may be as many pins p as desired on 3 on the pattern-wheel I the pattern-wheel P, so as to shift the platering more frequently than-once in each revolutlon of the pattern-wheel, as shown in Fig. 2. Thepin controls the number of courses in a -certain-designi. a, when any pin-p operates lever'V the ring I will be shifted,
